To use this feature, do the following: 1. Move the shift lever to the MANUAL MODE (M). When in the MANUAL MODE, the transmission's current gear range will be the highest attainable range with all the lower gears available. 2. Press the plus/minus buttons to upshift or downshift selecting the desired range of gears for your current driving conditions. The Range Selection Mode allows you to control the vehicle's engine and vehicle speed while driving down hill by allowing you to select a desired gear. The DIC shows the six available ranges with the highest attainable range shown in brackets. See Driver Information Center (DIC) on page 3-51 and DIC Operation and Displays on page 3-52 for more information. While using the Range Selection mode feature, cruise control and the Tow/Haul mode can be used. While at a stop, selecting the second gear range using the Range Selection system, will allow the Allison Transmission® to limit torque to the wheels after it detects wheel slip, preventing the tires from spinning. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. Cold Weather Operation (Allison Transmission®) On cold days, approximately 32°F (0°C) or colder, your automatic transmission is designed to shift differently. The transmission uses a warm-up mode shift schedule until the engine reaches normal operating temperature. While the transmission is in warm-up mode it is normal for transmission upshifts to be delayed or held longer. This feature improves heater performance by giving quicker vehicle warm-ups. When temperatures are below −13°F (−25°C), the transmission will prevent certain operations to protect against damage. When active the DIC will display the message "Trans in Warm-up". See DIC Warnings and Messages on page 3-54 for more information. Low Traction Mode (Allison Transmission®) If your vehicle has the DURAMAX® diesel engine and the Allison Transmission®, it is equipped with a Low Traction Mode that assists in vehicle acceleration when road conditions are slippery, such as ice or snow. 2-29
